Abstract
A gas turbine group is provided with at least one cooling apparatus for cooling the working medium before and/or during the compression. The cooling power of the cooling apparatus can be adjusted by suitable means. A controller controls the cooling power of the cooling apparatus as a function of a control deviation in the useful power of the gas turbine group. The cooling controller interacts with other controllers of the gas turbine group in such a way that the gas turbine group is itself always operated at least close to its full load operating state. In this context, it is preferable for the inlet guide vane row of the compressor to be maximally open, and for the hot-gas temperature on entry into the turbines to be controlled so that it is constantly at an upper limit value.
